Dear Torquil,

You are right, a function equivalent to "add_fem_name" do not exist for
integration methods. Of course, since the two systems for fems and
integration method derive from the same mechanism (dal_naming_system),
the same function can be easily added to It
should be as follow:

void add_integration_name(std::string name,
            dal::naming_system<integration_method>::pfunction f) {
    dal::singleton<im_naming_system>::instance().add_suffix(name, f);

I add it to the svn version of getfem.
